Where readiness, mapping, and ASP choice come together.
Implementation is where your readiness assessment, tax mapping, and ASP choice come together — connecting your systems, testing data flows, and going live with compliant e-invoicing.
% At A Glance
Connects your systems to your chosen ASP
Configures invoice data flows and formats
Supports you through go-live
Who Needs This
If you've chosen an ASP, this is the next step.
Businesses that have completed, or are ready to start, technical implementation of e-invoicing — typically after a readiness assessment and ASP selection.
Timing
Plan for testing time before go-live.
Implementation should leave enough time for User Acceptance Testing before you rely on the system for live transactions — build that testing window into your project timeline from the start.
What You'll Need
Documents for e-invoicing implementation.
ASP integration or API documentation
Finalized tax mapping
Sample invoice data sets
Current system access or credentials for configuration, as applicable
Why This Matters
What's at risk with a rushed go-live.
Rushing implementation without proper testing risks errors once live
Skipping validation increases the chance of rejected invoices after go-live
A managed implementation reduces disruption to your invoicing during the transition

Common questions
Frequently asked questions on e-invoicing implementation.
What does e-invoicing implementation involve? ⌄
Connecting your systems to your chosen ASP, configuring how invoice data flows, and testing that it works correctly before you rely on it for live transactions.
How long does implementation take? ⌄
It depends on your systems and how much integration work is needed — we'll give you a clear timeline after reviewing your setup.
What if I haven't done a readiness assessment yet? ⌄
We recommend starting there so implementation is built on a clear plan — see our Readiness Assessment page.
Is testing part of implementation? ⌄
Initial data validation is, but full User Acceptance Testing is its own structured step — see our UAT page.
Do you work with any ASP? ⌄
Yes — implementation support is built around whichever Accredited Service Provider you've chosen.
